IMPROVED CONSTRUCTION 0F GUIDES OR CHUTES FOR TURBINE WHEELS.

Specication forming part of Letters Patent No. 14,793, dated May 6, 1856.

To all whom t may concern.'

.Be Ait known that I, JOSEPH BAs'rIoN, of Theresa, in the county of J efferson and State of New York, have invented certain new and useful Improvements in Constructing Chutes for Turbine Vater-l/V heels; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

The nature of my invention consists in a new and improved mode of constructing the chute for turbine water-wheels, which mode enables me to impart the proper direction to the water when coming in contact with the wheel, also to regulate and govern the quantity of water discharged in a specified length of time.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure l is a top or plan view of the chute with same being open for the passage of the water to the wheel. Fig. 2 is an inverted View with the chute closed.

Similar figures in the several views refer to similar parts.

A represents a plank of suitable dimensions, to which I secure the stationary part of the chute.

B represents a conical center having an aperture in the top througlrwhich the wheelshaft passes, said center being heldin a stationary position by means of curved supporters O O, Fig. 2, which perform the double purpose of supporting the conical center and acting in conjunction with the movable part for graduating or closing the chute. Said supporters are provided with a flange c c c, as seen in Fig. 2, which forms an entire circle and is secured to the plank by any suitable means, thus giving permanency to the supporters C C and center B.

D E F are the adjustable part of the chute,

'which in form somewhat resembles the frustum of a cone inverted, the minor base of which if it were a perfect frustum would closely encircle the base of the conical center; but it may be seen by examining Fig. 1 that the parts D D are lin the form of a true cone and that the parts E E form part of a circle of a diameter less than that of the cone D Ds base. Bythis arrangement it may be seen that I form a chute I- I through the side of the cone, which imparts the desired direction to the water as it passes to the wheel. The flange g supports the movable or adjustable part of the chute and keeps it in place, said iiange g being secured between flange c, Fig. 2, and segments J J, Fig. l. K is a stop on flange g, which comes in contact with segment J when it is closed. The conical parts D D, Fig. l, correspond in their inclination and curvature with supporters C C, Fig. 2, and lit closely to them when the chute is open.

Fig. l represents the chute open. Now, to close the same we have only to revolve the movable part in the direction of the arrow, Fig. 1, until parts D D shall assume the position as shown in Fig. 2.

To graduate the quantity of water discharged to any desired volume, we have only to adjust the movable part accordingly.

I-Iaving thus fully described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is-

The stationary conical center B, in combination with the adjustable parts D E F-and supporters C O for the purpose of graduating the quantity of water discharged and giving the desired direction to the same, the whole being constructed and arranged as herein described.

In `testimony whereof I have hereunto set my hand and affixed my seal this 24th day of March, 1856.
